The UK is to delay declaring full operating capability (FOC) for its Lockheed Martin F-35 Lightning fleet, with a government minister saying it will now happen in 2025 rather than the earlier stated 2023.

At this time, 42 (the number is now 37) of the 48 contracted aircraft would have been delivered, and HMS Prince of Wales would be fully operational as the Royal Navy's second Queen Elizabeth-class aircraft carrier.
